SPECIFICATION forming part of Letters Patent No. 319,999, dated June 16, 1885.

' Application filed May 26,l.1.8,f* (No model.)

To all whom it may concern-.-

Be it known that I, GEORGE E. POTTER, a

citizen of the United States, residing at Paliner, in the county of Hampden and State of Massachusetts, have invented new and useful Improvenientsin Blind-Operating Apparatus, of whichlthe following is'ga specification.

This invention relates to improvements in window-blindoperating devices adapted to be operated fromv the Ainterior of a building, the object being toiniprove. the details of the construction of such apparatus, as hereinafter set forth. y

In the drawings forming part of this speciiication, Figure 1 is a plan view representing, partly in section, a portion of a building at the corner of a window, and a part of a blind hinged thereto, and having connected with thenlatter blind-operating devices embodying my invention. Fig. 2 is a similar view to Fig. l, but showing the position ol" the operating devices when the blind is opened. Fig. 3 is a side elevation, partly in section, of a portion of a building inside of and near the window.

In the drawings, Ais a part of the wall of a building. D is the inside casing. B is the window-janib.lB2 is the window-seat. b is the window-blind, and c is the blind-hinge.

The letters a and o2 indicate the positions of the windowsashes.

The window-blind bis hung in the ordinary way by two hinges, thelower one of which c, is shown in the drawiiiigs'.

To operate the blind b from within the house, the following-described devices are employed: A metallic or other suitable bar, d2, having a handle, d', thereon, is inserted in a passage through the wallof the building and one leaf of hinge c, or a suitable metal guide-plate. A metallic washer, o, surrounds said passage on the inside casing, D. A short bar, a Y", is

Lhinged to the end of bar d2 atf, one side of which isprovided withv serrations w, and a third bar, d, having one side thereof serrated to match bar d2, and having a slot in it at said serrated portion, is secured to bar d by a screw, m, which passes through said slot and into the last-named bar. The bar d2 is provided with notches fu on its under side, of' 5o proper width to engage with the edge of the washer o, and bar d has a curved projection.'

a2, on one side of it, which, when the saidA ing in the plate of hinge c, through which barA d passes.

The above-described handled-bar construe-'f ,l

tion constitutes practically a single bar adapt-y ed to have a sliding movement in the passage through the wall of the house. is jointed at f, in order that the handled end thereof may be dropped down parallel with the inner wall, as shown in Fig. 3, t0 look the blind open.- The lapped and serrated por.- tions fl and di provide means wherebv, the aid ol" screw m, the barinay be elongated or shortened to adj ust it to walls of different thicknesses. The notches o in ythe part; d provide means for securing the bar in differy ent positions by engaging the notches with the edge of the washer o, and thereby swing- Said bari ing and holding the blind more or less open.

rlhe curved projection x on the side ofthe bar d serves to make the latter more rigid when the blind is shut, bind in the opening in the e through which it passes.

Between the outer end of the bar d and the blind c are secured three lever-bars, e e e,

by causing the bar to f plate of the hingey Aj one being secured by one end thereof to ythe y n blind by the bolt e', and the two others pivoted together and to the last-named one and to the end of said bar d.

Bar d and the two succeeding leverbars`e have inclined shoulders 5 formed thereon a little back of their pivots, against which the adjacent edges of the bars e are brought to bear when the handle-bar is moved to open and shut the blind,` and whereby the latter is made to swing. 7Willen the blind is open, the l said two intermediate lever-bars enter within the passage in the wall, as shown in Fig. 2.

When the Withndescribed devices are usedv I 0u heavy shutters, the wheel 55 (shown in full in Fig. 2 and 1n dotted lines in Fig. 1) may be hung on the hinge-pin, and when bar d is op-y erated 1-,0 open the shutter the lever-bars e' are Supported by the border of said Wheel length of the handle-bar may be varied, the I against any lateral movement which too great lever-bars e, and blind c, combined and operstrain might cause. ating substantially as set forth.

What I claim as my invention is- GEO.' E. POTTER. 5 The handlebar consisting of the bar d2 and Witnesses:

the bar d2, hinged together, and the bei' d, H. A. CHAPIN, edjustably attached to the latter, whereby the J. D. GARFIELD.
